SiPixelCluster overview

Located in DataFormats/SiPixelCluster/interface, the SiPixelCluster.h contains the declaration of the SiPixelCluster class.

From the source file's header:

Quote

Class to contain and store all the topological information of pixel clusters: charge, global size, size and the barycenter in x and y local directions. It builds a vector of SiPixel (which is an inner class) and a container of channels.

In it, three helper subclasses are contained:

• Pixel
• PixelPos
• Shift
